hello

I have 2 MatrixXd, and I hope to construct one MatrixXcd from them, how can I realize it?

I checked the manual, but couldn't find.

It's easy to read in numbers for a simple MatrixXd, but I couldn't find similar way to input data into a complex MatrixXcd, did I miss something?

loop over the values of the matrix and use std::complex

Code: Select all

complexmat.coeffRef(i,j) = std::complex(Real, Imag)


there is a more direct solution:

Code: Select all

MatrixXd r, i;
// ...
MatrixXcd c;
c.resizeLike(r);
c.real() = r;
c.imag() = i;
